This 18K yellow gold Foundrae Snake Bookends diamond ring consists of two separate pieces that can be stacked together. The engraved and polished bands are finished with 0.02 carat white diamonds as eyes. The interior is engraved with a hallmark and maker’s mark. Ouroboros is an ancient symbol of a snake eating its own tail, representing eternity. That makes sense, as we’ll wear this Foundrae ring forever.
